s invention relates to a transfer tail der I i'cr coning and similar machines and has for its satisfactory manner than has been heretofore accomplished by manual operations.

It is customary in warping or knitting from cone packages of rayon yarn to tie the end of one cone package to the beginning of another package so as to avoid stopping of cone creels or knitting machines when the first package runs 0d. In order thatthe end of one package can be tied to the beginning of a second package it is the general practice in winding such cone packages for the coming operator to wind by hand several turns of yarn around the cone-center near its base and below the main wind or traverse of yarn, before placing the cone-center on the spindle to wind. Then several turns can be unwound when the cone is used and thus give length enough olyarn to tie to the beginning of a second cone. These several turns of yarn are called the transfer tail.

This invention consists of a suitable guide so placed that when the traverse frame back is in the open position away from the spindle, the thread passes from the supply through the regular traverse guide and then behind or in back of the transfer tail guide This positioning of the thread is accomplished when the operator after threading through the regular guide, wraps the yarn around the bare metal spindle or cone holder and when the cone-center is then forced over the spindle it carries the thread along its lower edge to the back or wide diameter end of the spindle. This carries it beyond or behind the transfer tail guide so that when the poweris appliedto the spindle and the spindle rotates in normal clockwise direction' all of the yarn is I wound at the base of the 'coneuntil. the. traverse .Irame back-is raised. or, closed to the regular starting positions The interval of time during which the operator permits'the spindle to rotate with the traverse frame in the: open position is determined by the length of transferztailidesired; The average length of tail, however, isobtained by permitting the: traverse :guide to make from will give I from, nine tq' twelve (coils; or wraps of v na he-tr er ail.

In forming the transfer tail, ii the de ids the yarn in one fined position the W i. t is invariably underwound or overwound, or in other words there is no control of the d, so that the creeling operator or knitter will have dimculty in unwinding the transfer t without snarling or catching. In addition, should the tail be left on the cone, such an underwound or overwound condition would prevent proper transierring from one cone to another as it would cause excessive thread breakage at t int.

ing motion to the thread with the result that the actual horizontal traverse motion of'the regular 1 il guide is reduced down to give t w 1 ature traverse motion to the thread as it is wound onto the transfer tail.

Asupporting-arm -iji is 'secur to to the traverse bar, and has an upper end jon which 1.

HM bl passes over a baildi, H I V According to "*the'presentdnventio thisv chine is preview. w hi were i shown in Figs. 4 and 5. This guide preferably comprises a length of wire having an eye 23 formed in one end, and an upstanding finger 24 at the other end. This guide is mounted as shown in Figure 1, on a stationary part of the winding machine, as by means of a screw 25 passing through the eye 23.

The body of the guide 22 extends substantially horizontally under the cone II, but is preferably inclined in two directions, slightly upward and slightly away from its stationary mounting. The finger 24 is substantially vertical in a plane parallel to the axis of rotation of the cone, but is inclined toward the other end of the cone.

In operation, after threading through the guide 20, when the arm I3 is in the open position away from the spindle as shown in Figures 1 and 2, the free end of the yarn is wrapped around the spindle or cone holder ID as shown at 30. The cone center H is then forced over the spindle, and carries the thread along its lower edge to the back or wide diameter end of the spindle, as at 32.

This position is beyond the finger 24, so that as shown in Figures 1 and 2, the yarn from the guide 20 passes over the transfer tail guide 22, and is retained by the finger 24.

Power is now applied to the spindle l0, while the transfer frame back carried by the arm i3 is still in open position, and all of the yarn is wound at the base of the cone. However, even in the open position of the arm IS, the guide has its usual traverse motion. The variations in tension produced by this traverse motion while the yarn is retained by the finger 24 cause the yarn to ride up and down the inclined surface of the finger 24 a slight amount, which produces a miniature traverse motion sufficient to lay the transfer tail in regular convolutions.

When the winding of the transfer tail has been completed, the operator merely releases the arm ll, which swings to its normal winding position shown in Fig. 3. It will be obvious from an inspection of this view that this motion of the guide 2. pulls the yarn free of the finger 24, because the guide 20 rides on the surface of the cone-center while the finger 24 is spaced therefrom. Of course the regular winding builds up the thickness of the package and the guide 20 riding thereon moves outwardly therewith, but the finger 24 being located to direct the transfer tail onto the base of the cone below the package, is laterally spaced to clear the package as it increases in diameter.

From the foregoing description it will be readily apparent that thepresent invention has the following advantages over the former manual procedure in winding a transfer tail:

1. Saving of time and labor.

2. Complete elimination of the running or dis-' placing of'twist in the yarn due to the unavoidable passing of the thread between thumb and finger of operator.

3. Elimination of staining of yarn from oil on the operators fingers.

4. The first layer or traverse of yarn on the regular cone traverse after the tail is wound by the manual method must be laid on in whole or part of a traverse manually by the operator. Any irregularity of the lay of this thread by hand can cause a half-hitch at the critical part of the transfer to cause failure of the same. This device permits the lay of this first traverse with the same precision and regularity as the balance of the cone is wound thus eliminating any possibility of half-hitches or underwinds.

5. Furthermore any opening of twist at this first layer of yarn on the full width traverse by the passage of the thread between operator's thumb and finger will cause the last layer of yarn to cling to the fuzz" or velvet finish of the paper cone center itself. As the thread is put under tension during transferring such open twist will close up so that the fuzz or nap on the surface of the paper center is gripped between the filaments of the yarn. Faulty transfers owing to the yarn breaking from these causes are eliminated by winding this critical layer or traverse of yarn by this mechanical means.

6. Frequent transferring difficulties are caused by winding the tail manually too high or too low at the base of the cone center. When wound too high the transfer tail is buried by the actual cone traverse of yarn so that several ends or false tails are produced when the creeling operator attempts to use the transfer tail so wound. When wound too low on the cone center the tailis pinched and damaged by the perforations in the trays of the shipping cases and when .the double use of the tail described hereafter is employed the residual tail is damaged or pinched by the pads or standards on the cone creel. The use of this device eliminates the foregoing .difliculties, in that each tail is wound at a definite fixed and proper position at the base of the cone center.

7. Shiners have been caused by the yarn at transfer tail and first layer on traverse being strained or stretched by the operator when starting a spindle. This device permits winding this portion of the thread with a minimum of yarn tension.

8. As the end of each transfer tail wound by this device is completely covered over or buried by the miniature traverse wind of the tail it permits an easy drawing of! of as many coils of yarn required for tying to the second cone. This will leave a residual tail on the cone which may be again used should it be necessary to remove one set or type of yarn from the creel in order to put on another type or denier. At present when this is done in the customer's mill the remnant cones must be run of! subsequently without transfer tails as these are broken off during the first set up.

9. With the end of the tail so buried and locked into position permits the tying of the outside end of the cone direct to the inside or tail and to facilitate finding of the transfer tall by the creeling operator as well as eliminating the use of one vgummed label which is used at present to fasten the transfer tail to the inside of the cone-center. This method also eliminates the notching of the base of the cone with scissors to prevent chafing of the yarn which passes around the lower edge of the cone-center and so increases the life of reused cone-centers.
